' SPRING.

T 0 all whom itmcty concern:

Beit known that I, CHARLES EDGARMAN- NERS, a'subjectof His Majesty theKing of Great Britain, residing: at Glenville Glen, Crafers. in theState of 1 South Australia, in the Commonwealth of Australia, haveinvented certain new and useful Improvements in and Connected WithSprings, of which the following is a specification. v

My invention relates to improvements in and connected with springs andis intended to apply more particularly to what I are termed coil springsand half-coil springs for furniture and upholstery and for the cushionsof motor cars and the'like.

Hitherto springs ofthis nature-have usually be'en held in positio-n'bystrips of webbing to which they have been-stitchedor to a lining ofHessian or other fabric, and more recently cross wires have beenintroduced been attached by metal clips.

The special object of my invention is to construct the springs in such amanner that they contain means for attachment to; the wires of the frameas an integral portion of the spring, anauxiliary attachment beingprovided if so desired to assist in keeping the springs in theirrelative positions.

In carrying my invention. into efiect I form loops, recesses orhook-like structures in suitable positions by twisting or bending thespring substantially in the manner hereinafter' described and asillustrated in the accompanying drawings wherein Fig. 1 is a sideelevation of a spring.

Fig. 2 is a plan of Fig. 1.

Fig. 3 is a plan of a spring showing different arrangement of the bentor looped portions for use with parallel frame wires.

Fig.4 is a plan of a spring with loops for cross wires also showingattachment to an adjacent spring.

Fig. 5 is a side elevation of a spring showing cross wires engaged inloops or kinks.

Fig. 6 is a side View of a spring showing cross wires engaged inhook-like formations whichare-bent upon inturned top and bottom ends ofthe spring wire.

Fig]? is a plan showing the upper por Specification of Letters Patent.Pate t ed F b 77, 1922 Application filed August 26,1920. Serial No.406,099.

Fig. 9 illustrates the hook portion of inturned end after it has beenfinally bent and of reference are used to denote similar orcorresponding parts wherever they occur. v

In the drawings the colls of the wire spring are indicated by thereference "letter a, the

spring being either of spiral construction as n F 1g. 1 or it mayconsist of rings of equal diameter as in Fig. 6.

In Figs. 1, 2 and 4 I have illustrated loops or eyelets 6 arranged atright angles round the periphery of the spring wire by merely bendingthe wire upon itself as clearly indicated, the loop thus formed being ofjustv fsuificient diameter to accommodate the cross wire 0. In Fig. 3 Ihave shown two similar loops'opposlte to each other, but thecorresponding' loops which are'at right angles are twisted or deflectedoutwardly so thatif thev frame is built up of parallel wires they canreadily be accommodated in the side loops as will be well understood.

It may not always be necessary or convenient to form complete loops oreyelets in the periphery of the wire and I have therefore provided forthe accommodation of the cross wires in kinks or recessescorrespondingly marked 6 in Fig. 5 and likewise arranged at right anglesto each other. These are preferably bent alternately upwards anddownwards, the arrangement being such that the cross wires incombination with the spring interlock each other and preventdisplacement without'necessitating an :as shown in plan in Fig. 8. i Theportion which forms the loop is then bent downwards at right angles tothe part a and.

the free end marked a in Fig. 8 is also bent downwards parallel to theloop bend so as to form an arch. This structure provides for theaccommodation of both cross wires in the centre of the spring as will bewell understood upon reference to Fig. 9 of the drawings.

In Fig. 4 I have shown a small bridgepiece at d for keeping adjacentsprings in their relative positions. This bridge-piece is not forattaching the springs to the cross wires but is to preventtheirdisplacement on their mountings as ithas been found in connection withsome attachments that the springs sometimes work apart and in othercases they come together and cause rattle. The bridge-piece for thispurpose may have slots or holes at each end to facilitate its attachmentto the structure so that the cross wires will not form an impediment,but it is turned back upon itself so as to embrace the spring wires andcan be cleated with the aid of pliers or other implement in order thatit may firmly hold the spring wires and stood that this may be furnishedwith loops or hooks of the nature already described, or

a single or double loop or hook may be 7 formed thereon, and that thebent 'or looped end shown in Fig. 8 may be used to' support asupplemental attachment.-

Having now fully described and ascertained my said invention and themanner in which it is to (be performed, I declare that what I claim is Adevice of the character described including upper and lower crossedframe wires extending substantially at ri 'ht angles to each other, andcoiled springs interposed between said upper and lower frame wires andhaving their axes substantially aligned with the intersecting points ofsaid crossed frame wires, each of said springs being provided with aninwardly projecting end portion bent back upon itself to form a hookhaving an open end and a closed end, the closed end being substantiallybelow the planerof said inwardly bent portion and an intermediateportion of said hook being arched upwardly to overlie one of said framewires and at opposite sides of the other cross frame wire, said closedend of said hook being engaged under the last hamed. cross frame wire,whereby the hook and said crossed I frame wires are interlocked againstlateral displacement.
